What happened was that when flow director part (in rte_eth_ctrl.h)
is removed from always being included by rte_ethdev.h, then this
code would not build.  The code relied on the include cascade:
   rte_ethdev.h
     rte_eth_ctrl.h
       rte_flow.h
         rte_ip4.h
           arpa/inet.h

Maybe other things are getting this as well?
The DPDK IP headers should rely on the Linux definitions, but that
is  a different issue.
